DOZ-6850 Online Dissolved Ozone controller
Description:
● DOZ-6850 online Dissolved Ozone Controller is a micro computerized precision instrument. ● Adopt the advanced non-film constant voltage sensor, no need to replace the diaphragm and pharmaceuticals. High sensitivity, rapid signal response, accurate measurement, stable performance, easy maintenance. ● The large LCD display, English menu operation. ● Multi-parameter display: The value of dissolved ozone, temperature, output current and has range transfinite alarm. ● With factory reset function, slope correction function. ● Automatic/Manual Temperature Compensation: 0℃ to 60℃ ● The control interface: two groups of ON/OFF relay contact, divided into high and low alarm signal photoelectric isolation output. ● The third group relay: automatic cleaning control function analog output.(Optional) ● Relay lag quantity any setting, relay load 3 A 220 vac/24 VD ● Communication function (optional): RS-485 communication interface, 4 to 20 mA current output corresponding to the Ozone value can be set freely. ● Hysteresis amount can be set freely to avoid frequent switching relay action ● Watchdog function: to ensure that the instrument will not crash ● Core devices from famous foreign brands ● Restore the factory settings. Power-down protection> 10 years ● IP65 protection enclosure. Application: Widely used for continuous monitoring and control of ozone content in aqueous solutions for drinking water treatment plants, canning plants, drinking water distribution networks, swimming pools, cooling circulating water, water treatment etc. Main technique Specification:|
